Supposedly FTTH-rich countries contribute much moreto P2P networks because they have a symmetrical connection and are moreattractive to the P2P clients.And how much does being in the same AS help compare to being geographicallyor hopwise apart?That we don't yet know for sure. I've been reading a lot of research onit, and doing some experimentation, but there is a high degree of correlation between intra-AS routing and lower latency and greater capacity. Certainly a better correlation than geographic proximity.
As is frequently pointed out, here and elsewhere, network topology != geography.
Using AS proximity is definitely a help for resilience though, same-AS sources and adjacent AS sources are more likely to remain reachable in the event of transit problems, general BGP flaps and so on.
Do you actually inject any BGP information into Venice ? How do you determine otherwise that two nodes are in the same AS (do you, for example, assume that if they are in the same /24
then they are close in network topology) ?
